Ever since that day when I was 11 years old, and I wasn't allowed in a photo because I wasn't wearing a tennis skirt, I knew that I wanted to change the sport.

I always respect right off the bat because we are human, but then over time you learn who the person truly is, just like they learn about you. Hope it works out really well, and you hope that builds a stronger connection over time. You can't be friends with everybody.

Pressure is a privilege ... it's what you do with it that matters.

I've never cared that much for cementing my place in history. Sports is so transitory, so ephemeral. It just seems like so much nonsense comparing me to Helen Wills Moody or Suzanne Lenglen or anybody else from some other time. One lesson you learn from sports is that life goes on without you.

It is very hard to be a female leader. While it is assumed that any man, no matter how tough, has a soft side... and female leader is assumed to be one-dimensional.

I always listen, I ask children, I even ask adults in tennis, "What are your children playing?" And most of the time it's not tennis. It's pathetic.

When I was playing, we didn't have to compete against everybody in the world. Now it's a truly global sport, so the competition's much greater, just like it is for our children in every other area, whether it be in science or technology or whatever you talk about.
